Qube (stylized QUBE) was an experimental two-way, multi-programmed cable television system that played a significant role in the history of American interactive television. It was launched in Columbus, Ohio , on December 1, 1977. [ 1 ]
Continuous Automatic Warning System is the cab signaling systems in Ireland. The system makes use of 0, 50, 120 and 180 ppm codes using a 50 Hz carrier current. Additional codes are used on some rapid transit lines. Automatische treinbeïnvloeding is the Dutch cab signaling system. It makes use of 0, 75, 96, 120, 180 and 220 ppm codes using a ...
Ceragon designs and manufactures high-capacity communication systems for wireless backhaul, mid-haul, and front-haul. It addresses the segment of the cellular market that connects a typical cell site to an operator's core network (backhaul) and different cell site functions that reside in separate geographical locations (mid-haul and front-haul).
Transit Wireless is an American telecommunication company founded in 2005, based in New York City. It was formed as a consortium of several entities, including Dianet Communications. It was formed as a consortium of several entities, including Dianet Communications.
In the newer ABTC-M block control the KLUB-U systems decode signals by TETRA digital radio including a remote initiation of a train stop. In those areas the train position is derived from a satellite navigation system (GPS or GLONASS). The ITARUS-ATC connects the KLUB-U in-cab system via GSM-R digital radio with the ERMTS Level 2 RBC block control.
Advanced Civil Speed Enforcement System (ACSES) is a positive train control cab signaling system developed by Alstom. [1] The system is designed to prevent train -to-train collisions , protect against overspeed, and protect work crews with temporary speed restrictions.
Account-based: New York's OMNY OMNY, Chicago's Ventra system [21] (used by CTA, Pace and Metra), Brisbane's GO card system, and London Oyster Cards are some of Cubic's account-based products. Mobile: Cubic has deployed mobile applications in multiple locations in the United States and was the first to launch transit cards within the mobile wallet.
Wi-Charge does claim that using infrared light for long-range wireless power has advantages over using radio frequency or ultrasound because of two main reasons: Physics. Because of their very short wavelength, infrared beams diverge (see Diffraction) much less than technologies with longer wavelengths. This means that the diameter of the beam ...
